GKE 1.16.9 Prometheus, grafana per pod details not working?

I have a GKE cluster running kubernetes 1.16.9. I'm trying to get a monitoring system working using Prometheus, and Grafana.

The dashboard I'm using is the standard "Kubernetes Cluster Monitoring" https://grafana.com/grafana/dashboards/315

When I import it though, I can't see the pod-by-pod CPU/Memory usage, I just see "value": grafana dashboard not working image

I have another cluster with an almost identical setup using kubernetes 1.15 and the dashboard works perfectly showing each pod and the usage of each pod.

Why is this the case? I'm fairly new to understanding prometheus/grafana and how all this works together.

working image

What could be causing this issue? The metrics are showing, and kubectl top pod shows up... so I think metrics-server is working well...

Any tips on trying to debug this?

You are not alone with this problem. The things are like that: pod_name and container_name labels coming from the kubelet were deprecated in 1.14 in favor of pod and container, then removed in 1.16

Removed metrics

Removed cadvisor metric labels pod_name and container_name to match instrumentation guidelines. Any Prometheus queries that match pod_name and container_name labels (e.g. cadvisor or kubelet probe metrics) must be updated to use pod and container instead. (#80376, @ehashman)

so as per above - Any Prometheus queries that match pod_name and container_name labels (e.g. cadvisor or kubelet probe metrics) must be updated to use pod and container instead

Very similar question for your reference - Grafana dashboard not displaying pod name instead pod_name

btw, have you tries this one? https://grafana.com/grafana/dashboards/11143
